Jangheung is a small county in Jeollanam-do that is located near the sea of Boseongman Bay, and by the big lake created by Jangheung Dam and Tamjingang River.

The Jangheung Jeongnamjin Water Festival (also called the Jeongnamjin Aqua Festival) is held each year around the end of July. Unlike conventional festivals with exhibits, performances and shows, the Jeongnamjin Water Festival aims to offer something different by having summer and water-themed events where visitors can enjoy a multitude of fun and exiciting summer games and activities.
